[0053] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] The wind turbine start-stop control method provided in the embodiment of the present application can be applied in the application environment shown in Figure 1. Among them, the terminal 102 communicates with the server 104 through the network, and the terminal 102 can be used for collection. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The data storage system can be used to store the temperature data and current data collected by the terminal 102, and can also be used to store the relevant data of the actual wind speed curve under the historical wind turbine operation scene. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.

[0055] In an exemplary embodiment, as shown in FIG2 , a fan start-stop control method is provided, which is described by taking the method applied to the server 104 in FIG1 as an example, and includes the following steps S202 to S208 . Among them:

[0056] Step S202, obtaining temperature data and current data in the current fan operation scenario.

[0057] Exemplarily, the server 104 can control the fan to maintain the running state at the preset initial wind speed within a preset time period, wherein the preset time period can be 10 seconds. Exemplarily, after 10 seconds, the terminal 102 can read the real-time temperature of the environment or the inside of the device by connecting to a temperature sensor near the fan, such as NTC (Negative Temperature Coefficient). The NTC sensor will produce a corresponding resistance change according to the change of the ambient temperature. The controller calculates the accurate current temperature value by measuring the voltage divider value of the sensor and combining the internally calibrated temperature-voltage relationship table. Further, the server 104 can first determine whether the NTC wiring harness is connected. If the NTC wiring harness is not connected, the temperature of the welding machine cannot be determined. For safety reasons, the fan will be turned on all the time; the detection circuit includes a pull-up resistor with a fixed resistance value, and the NTC is connected as a pull-down resistor to play a voltage divider role. Therefore, when the NTC changes, the voltage measured at both ends of the NTC will also change accordingly. According to the relationship between the NTC resistance value and the temperature, the relationship between the voltage and the temperature can be calculated, thereby realizing the temperature detection.

[0058] Furthermore, the terminal 102 is also connected to a current sensor to monitor the real-time value of the current when the fan is running. The current sensor is usually a Hall effect sensor or a shunt, which can output a signal proportional to the current size according to the load of the fan. The terminal 102 samples the current signal, converts it into a digital value, and records the current amount.

[0059] For example, the server 104 may acquire temperature and current data at a fixed time interval (e.g., every second) and store the data in a memory buffer or local storage for subsequent trend analysis and wind speed adjustment. At the same time, the server 104 may perform preprocessing operations during the data acquisition process, such as filtering transient noise or abnormal signals, to ensure that the acquired data is accurate and reliable.

[0060] Step S204, determining the current wind speed curve according to the temperature data and the current data.

[0061] The current wind speed curve is used to determine the operating wind speed of the wind turbine in the time period at the current moment.

[0062] For example, the server 104 can process the collected real-time temperature data and current data to determine the current temperature change trend and current change trend. The server 104 can store the temperature and current data of the most recent period in a memory or cache, arrange them in chronological order, and calculate the difference between every two adjacent data points to obtain the temperature change rate and current change rate. These change rates can reflect the dynamic change trend of temperature and current in the current operating scenario.

[0063] Next, the server 104 can plot these real-time data as temperature curves and current curves. These curves reflect the fluctuations of temperature and current over time. For example, the temperature curve may show that the temperature rises steadily over a certain period of time, while the current curve may show periodic fluctuations. The server 104 can further analyze the slopes, peaks or troughs of these curves to extract key information, such as the speed of temperature rise or the range of severe fluctuations of current.

[0064] In combination with the analysis results of these curves, the server 104 can dynamically adjust the current wind speed curve according to the set rules. If the temperature curve shows that the temperature rises rapidly, or the current curve shows that the load increases, the target value of the wind speed curve will gradually increase, and the fan will accelerate; if both the temperature and current curves show stability or decrease, the wind speed curve will lower the target value and reduce the speed of the fan. By associating the temperature, current curves and wind speed curves, the server 104 realizes dynamic control of the fan speed and ensures a balance between fan operating efficiency and equipment protection.

[0065] Step S206, obtaining actual wind speed curves under historical wind turbine operation scenarios.

[0066] Exemplarily, the server 104 may select an actual wind speed curve under a wind turbine operation scenario according to a temperature change trend, a current change trend, a temperature change rate, and a current change rate.

[0067] For example, the server 104 can store and organize historical wind turbine operation data. When the wind turbine is running, the server 104 can record the current wind speed and related operation parameters in real time, such as timestamp, temperature, load current and wind turbine speed, etc. These data are usually stored in the form of time series in the internal storage device of the system, which may be a ring buffer, database or cloud storage.

[0068] When it is necessary to obtain a historical wind speed curve, the server 104 can query the historical data storage module and extract wind speed-related records according to a specified time range. For example, the user can set a time interval, such as the operating data of the past 24 hours or the past week. The controller reads the qualified wind speed data from the storage module and sorts and summarizes these data in chronological order. The sorted data will be converted into a wind speed curve, that is, the actual wind speed value corresponding to each time point. This curve clearly shows the operating status of the fan at different time points, such as the increase and decrease of wind speed, the stable operation interval, and whether the wind speed adjustment meets the equipment requirements. By analyzing this historical wind speed curve, the server 104 can evaluate the efficiency and stability of the fan operation, and provide an important reference for future prediction and regulation. If the wind speed curve shows that there are unreasonable fluctuations in certain time periods, the server 104 can further combine the temperature and current historical curves to find the specific causes of these fluctuations.

[0069] Step S208, correcting the current wind speed curve according to the actual wind speed curve to obtain the operating wind speed curve, and controlling the operating state of the wind turbine according to the operating wind speed curve.

[0070] Exemplarily, the server 104 may determine a correction weight according to the rate of change of the actual wind speed curve; and correct the current wind speed curve according to the correction weight and the actual wind speed curve to obtain the operating wind speed curve.

[0071] Furthermore, in the process of determining the operating wind speed curve, the server 104 can dynamically correct the change trend of the historical actual wind speed curve and the current actual operating conditions. First, the server 104 can calculate the rate of change of each time period from the historical actual wind speed curve, and this rate of change reflects the speed of increase or decrease of the wind speed over time. The method for calculating the rate of change can be to take the difference in wind speed between two adjacent time points and divide it by the corresponding time interval. For example, if it takes 5 seconds for the wind speed to increase from 10% to 20%, the rate of change is 2% per second. By analyzing the rate of change over a period of time, the speed of wind speed adjustment and possible over-adjustment or under-adjustment can be identified.

[0072] Next, the server 104 can calculate the correction weight based on these change rates, combined with the current operating temperature, current and target wind speed requirements. The correction weight can be a dynamically adjusted parameter used to determine the magnitude and direction of the wind speed correction. For example, when the change rate is too large and causes drastic fluctuations in wind speed, the server 104 can give a smaller correction weight to slow down the adjustment; when the change rate is too small and the wind speed response is slow, the server 104 can increase the correction weight to improve the adjustment efficiency. The size of the correction weight is usually calculated through a set of preset rules or formulas, which may include multiple factors such as the slope of the temperature curve, the magnitude of the current change, and the stability of the wind speed change.

[0073] Finally, the server 104 can use the correction weight to adjust the current actual wind speed curve to generate the final operating wind speed curve. The specific method is to enlarge or reduce the value of each point on the current wind speed curve according to the correction weight. For example, if the current wind speed is 50% and the correction weight is 1.1, the corrected wind speed is 55%. This correction process can be linear or the correction degree of different intervals can be differentiated by segmentation rules. The generated operating wind speed curve not only meets the current equipment requirements, but also effectively avoids drastic fluctuations or unnecessary delays, thereby achieving accurate and stable wind speed control.

[0074] In the above-mentioned fan start and stop control method, by obtaining the temperature data and current data in the current fan operation scenario, the current wind speed curve used to determine the operating wind speed of the fan in the time period at the current moment is determined according to the temperature data and current data, and then by obtaining the actual wind speed curve in the historical fan operation scenario, the current wind speed curve is corrected according to the actual wind speed curve to obtain the operating wind speed curve, and the fan operation state is controlled according to the operating wind speed curve. Not only can the fan operating wind speed be determined according to the temperature and current data, but also according to the historical actual wind speed curve, reference can be made to the use of the welding machine in the current scenario, so as to more comprehensively control the fan operating wind speed and improve the accuracy of the fan start and stop.

[0075] In an exemplary embodiment, as shown in FIG3 , step S204 includes steps S302 to S308 . Among them:

[0076] Step S302: determining a temperature curve according to the temperature data, and determining a current curve according to the current data.

[0077] For example, the server 104 can determine the process of the temperature curve based on the temperature data. First, the real-time temperature data is obtained from the temperature sensor, and the temperature data at each time point is organized into a curve to reflect the temperature change trend over time. In order to more accurately depict the temperature change, the server 104 can smooth the data to eliminate short-term noise interference and make the temperature curve more stable. The server 104 can determine the trend of temperature rising, falling or maintaining stability by analyzing the slope and fluctuation of the temperature curve. This temperature curve will serve as a key basis for controlling the fan. When the temperature reaches the set threshold, the control system will trigger the adjustment of the fan speed.

[0078] Similarly, the process by which the server 104 can determine the current curve based on the current data also follows similar steps. As a part of the terminal 102, the current sensor collects the current value of the fan load in real time and records it at certain time intervals. In order to improve the accuracy of the current curve, the server 104 can smooth the data to eliminate the impact of occasional current fluctuations. By analyzing the current curve, the server 104 can determine the changes in the load, such as the current increases when the load increases and the current decreases when the load decreases. The current curve provides a necessary reference for adjusting the wind speed of the fan, ensuring that the fan provides sufficient heat dissipation capacity when the load increases. The server 104 can fully understand the operating status of the fan by analyzing the temperature curve and the current curve at the same time, and make dynamic adjustments according to actual needs.

[0079] Step S304 , determining the wind speed change trend of the current wind speed curve by combining the temperature change trend of the temperature curve and the current change trend of the current curve.

[0080] Exemplarily, the server 104 may determine that the wind speed change trend is an increasing state when both the temperature change trend and the current change trend are in an increasing state, and may determine that the wind speed change trend is a decreasing state when either the temperature change trend or the current change trend is in a decreasing state.

[0081] Step S306, determining the wind speed change rate of the current wind speed curve according to the temperature change rate of the temperature curve and the current change rate of the current curve.

[0082] For example, the server 104 can dynamically determine the wind speed change rate of the current wind speed curve based on the temperature change rate of the temperature curve and the current change rate of the current curve, and the control system will combine the change trends of the two. First, the temperature change rate of the temperature curve reflects the rate of increase or decrease of the temperature over time, which can help the system determine the speed at which the current temperature rises or falls. For example, if the temperature changes very quickly, the system may need a higher wind speed to accelerate heat dissipation; if the temperature changes slowly, the adjustment of the wind speed may be relatively stable. The temperature change rate can be obtained by calculating the ratio of the temperature difference between adjacent time points in the temperature curve to the time interval.

[0083] Similarly, the current change rate of the current curve reflects the speed of the fan load change. If the current increases rapidly, it means that the load has increased, and the system needs to increase the wind speed to ensure sufficient heat dissipation capacity; if the current decreases, the load is reduced, and the wind speed can be reduced accordingly. In the current curve, the current change rate can be obtained by calculating the ratio of the difference between adjacent current values ​​to the time interval.

[0084] Combining these two change rates, the server 104 can calculate the change rate of the wind speed according to a preset rule or weight algorithm. Among them, the temperature change rate and the current change rate will have different effects on the wind speed change rate. For example, when the temperature change rate is large, the temperature requirement may be given priority to adjust the wind speed, while when the current change is large, the load factor may be more important. Through weighted average or other combination methods, the system finally obtains a comprehensive wind speed change rate.

[0085] Step S308, determining the current wind speed curve according to the wind speed change trend and the wind speed change rate.

[0086] For example, the server 104 can dynamically adjust the current wind speed curve according to the set rules. If the temperature curve shows that the temperature rises rapidly, or the current curve shows that the load increases, the target value of the wind speed curve will gradually increase, and the fan will accelerate; if both the temperature and current curves show stability or decrease, the wind speed curve will reduce the target value and reduce the speed of the fan. By associating the temperature and current curves with the wind speed curve, the server 104 realizes dynamic control of the fan speed and ensures a balance between the fan operating efficiency and equipment protection.

[0087] In another embodiment, the server 104 controls the fan to maintain an operating state at a preset initial wind speed within a preset time period, and then obtains temperature data and current data under the current fan operation scenario, thereby determining a temperature curve based on the temperature data and determining a current curve based on the current data.

[0088] When the temperature change trend and the current change trend are both in an increasing state, the wind speed change trend is determined to be in an increasing state; when the temperature change trend or the current change trend is in a decreasing state, the wind speed change trend is determined to be in a decreasing state.

[0089] Next, server 104 determines the wind speed change rate of the current wind speed curve based on the temperature change rate of the temperature curve and the current change rate of the current curve, and then determines the current wind speed curve based on the wind speed change trend and the wind speed change rate, thereby determining the operating wind speed of the fan in the time period at the current moment, and selects the actual wind speed curve under the fan operation scenario based on the temperature change trend, current change trend, temperature change rate and current change rate.

[0090] Subsequently, the server 104 determines the correction weight according to the rate of change of the actual wind speed curve, corrects the current wind speed curve according to the correction weight and the actual wind speed curve to obtain the operating wind speed curve, and finally controls the operating state of the wind turbine according to the operating wind speed curve.
